Abstract

A case (10) of a fluid control device (1) has an internal space that is partitioned by a partition wall (12) into an air blowing chamber (21) and a control chamber (22). A dividing wall (13) is disposed inside the air blowing chamber (21) to partition an internal space of the air blowing chamber (21) into a first air blowing chamber (21a) and a second air blowing chamber (21b). A fan unit (30) is housed in the second air blowing chamber (21b). A differential pressure sensor (41) senses a differential pressure between a pressure inside the first air blowing chamber (21a) and a pressure inside the second air blowing chamber (21b). A control unit (40) controls a fan (32) based on the sensed differential pressure. (Fig.1)
